IMPROVEMENT lN MACHINES FOR PULLING AND CUTTING STALKS.

Specilication forming part of Letters Patent No, 30.359, dated October 9, 1860.

To (LU whom, t may con/cern,.-

Be it known that I, H. SNYDER, of Dayton, in the county of Montgomery and State of Ohio, have invented a new and useful Machine for Pulling Ootton-Stalks and Cutting Standing Cornstalks; and I do hereby declare that the following is a full, clear, and exact descrip tion of the same, reference beinghad to the annexed drawings, making a part of this speciication, in which- Figure l is a side elevation of my invention; Fig. 2, plan or top view of the same; Fig. 3, a section showing the operation of the pullers or angular plates.

Similar letters of reference indicate corresponding parts in the several iigures.

The object of this invention is to obtain a simple and eiiicient machine by which old cotton-stalks may be eradicated or pulled out from the ground by the roots to make way for a succeeding crop, the invention being also applicable for cutting standing cornstalks.

The invention consists in the employmenty or use of two rotating wheels placed on a mounted frame and obliquely with its line oi' draft, said wheels being provided with hooks or cutters rotated from the groundfwheels of the machine, and used in connection with rotary cleavers, as hereinafter fully described.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents an axle having its wheels B B placed loosely on it. lThe ends of axle A are attached to two parallel bars, C C, the`front part oi" which form the thills of the machine.

To the outer side of each bar C there is permanently secured a block or head, D. These blocks form steps for the lower ends of inclined shafts E E, on each of which two pinions, F G, are attached. The outer pinions, F, gear into toothed rims I-I on the outer -sides of the wheels B B, and the inner pinion,

G, gear into toothed rims I at the inner sides of wheels J J, which are placed one at each side of the machine, the axles K of said wheels having their inner ends tted in the blocks D and their outer ends fitted in curved bars L, one end of which is attached to the back end of the bars C C and the opposite ends to a cross-plate, M, above the wheels I B B. The wheels J J are smaller than the wheels B B, and have an oblique position relatively with them, as shown clearly in Fig. 2. The upper ends of the shafts E E have their bearings in curved bars N N, which are at tached to the parallel bars C C.

To the outer sides of the wheels J J, at their peripheries, there are secured hooks O. These hooks may be formed of plates having oblique inner edges, so as to form V-shaped openings between them and the wheels J, as shown in Fig. 2.

Through the outer part of each shaftE a bar or rod, I), passes transversely. These rods P are shown in Fig. V2.

The operation ofthe machine is as follows: As the machine is drawn along, the wheels J J are rotated through the medium of the gearing F G H I in the direction indicated by the arrows, and the hooks O grasp the stalks and draw them from the ground with all the roots attached. The bars or rods P knock off the stalks from the hooks as the former approach the rods P.

From the above description it will be seen that two conditions are necessary in order that the machine may operate perfectly. First, that the wheels B B J J be in line with the rows; and, secondly, that the rods or. bars P rotate with such a speed as to present them selves properly to the hooks and knock oli' the stalks therefrom. In order to effect the former end, an adjustable axle may be used that is to say, one formed of two parts and capable of being extended or shortened, as may be seen in many agricultural implements; and in order to eiiect the latter end the rods or bars P should rotate as many times to each revolution of the wheels J as there are hooks thereon, and a proper relative position of the hooks with the rods must be preserved. This can be readily arranged by any mechanic of ordinary ability.

I would remark that, in order to prevent the casual derangement of the wheels J relatively with the wheels B B, ratchets may beplaced on the axles of the former and pawls made to engage therewith, so as to prevent any retrograde movement of wheels J in case the hooks engage with a deep-rooted stalk. `I would also B B, and4 provided With hooks or cutters O, remark that for harvesting corn the hooks may in -connection with the rotary 10ers or knockbe made with euttingedges to form knives. ers P, or their equivalents, essentially as and y Having thus described my invention, what for the purpose set forth.

I claim as new, and desire to secure by Letters HENRY SNYDER. Patent, is* Witnesses:
